Network Printers not showing up

[snydesdog]

I have a distribution business with a few satellite warehouses and I am trying to fix the printer situation at one our warehouses from our main location. Yesterday the manager had put in a new modem cause the previous one went down and after receiving it and hooking it up I had it bridged to our firewall so I assumes the same settings as before and everything is working fantastic and they can log on to our remote servers and do everything they used to be able to do but the network printers they have installed there are showing up as offline and we can not print to this remote printer from our main office which we used to be able to do. Could it be the switch the printers are hooked into went bad? I had one employee who was hard wired into the network switch for internet access and he couldn't access the internet so I hooked him up wirelessly and it works just fine. Any suggestions would be great as printing down there for orders is a neccessity and I would like to not have to travel if it is something simple. Thanks in advance for all your help!

Without being there to actually look at anything here is my assumption.

The "modem" you changed out was a modem/router combo device. Since you changed the router, the printer is trying to make a wifi connection to the old router, or if wired it probably has the wrong IP address sequence.

If the printer is wireless then you need to reconfigure each printer to the new network (even if you named the wifi network the same as the old one).
If the printers are wired via Ethernet then you need to go into the IP configuration and set the IP address.
If you do not know how to obtain the IP address or any of this then since this is a business you really should contact a local IT person who can set this up correctly in a much quicker time frame as hiring someone in the end will cost the business less money.

Thanks for the response!

The printers that I have are wired via ethernet into a switch and I went into my IP configurations on both my printer and my computer under the devices and printers under the printer properties and my IP address is the same as it was when I had the old modem from my ISP. The weird thing that has me stumped is I have other desktops with wireless adapters that connect just fine the wireless router and can access our remote server. Its just for some reason that the printers aren't being recognized on the network when all I really did was change ISP modems and then bridged the settings to my sonic wall to for it to adjust to those settings and everything worked as it should except for the printers. I have done this with one of our other satellites and everything worked great. Sorry for the lengthy response. Its just frustrating. Thanks again

Do this for me:

Ping printer IP address from computer.
Also will you tell me what the IP of the printer is, and the IP of the computer
(don't worry about giving local IP addresses, it is the IP address from your ISP that you don't want to post online)

Also go to Devices and Printers, right click the printer, select "printer properties" and tell me what the port says.

Hi, i believe this is the problem i'm having. I just got a new modem/router and ever since, my printer goes to sleep and says "offline" when I try to print something. I have already reconfigured the printer, it works while it's awake. After 5-15 minutes, it goes back to sleep, and won't print until I turn it off and back on again. I've tried hard restarts on the modem and the printer. I assigned a static IP. tested and works, but nothing has solved my problem, it still says "offline" and won't wake up! How do I get my printer to work great like it did with my last modem/router? it was flawless before..

What is the printer model?
Router model?
connection wired or wireless? If wired then is there a switch between router and printer?
